Abstract (en)
[origin: WO2011038921A1] The invention relates to a method for moving a machining unit (2) of a machine, in particular a press, wherein the movement comprises at least an approach phase and a subsequent machining phase, wherein during the approach phase the machining unit (2) approaches or is brought in contact with a workpiece to be machined, and wherein the machining unit (2) exerts force on the workpiece during the machining phase by moving the machining unit (2) while the same is in constant contact with the workpiece. The machining unit (2) is moved by means of a servo-mechanical drive unit during the approach phase and by means of a hydraulic drive unit during the machining phase.
